    Any recommendations for cleaning these clutch plates and friction plates? The spots you see are light rust. 1968 Husky sat for 15 years. Had to pry the plates off each other with my fingernail. Should I soak in Evapo-rust and then clean with a green scotch-brite and wd-40? That's how I clean rust off my table saw. Thanks. Here's a pic of the rust.

    clutch plates are replaceable, something to consider
    but you can clean those, you want some roughness on the metal and a reasonably clean fiber

    My 1970 400 Cross plates looked just like that when I refurbished it after years of sitting. I tried cleaning the plates and a light sanding. It was plagued with clutch slippage. Tried different cleaning methods and adjusting, then readjusting the springs, still slipped. I decided it must be the springs, until I talked to John at Vintage Husky. He said just replace the plates and it will work. He was right, new set of plates. Don't know if you'll have the same issues, but my suggestion is like 2premo above, consider a new set of clutch plates.

    Thank you all. I let them sit in evaporust overnight and they seem to be working. But I have not tried them with the engine running yet. Got a bit to do before that. And I've got John at Vintage Husky on speed dial by now (he's very helpful) so I may just get some new plates.
